Asthma

“Asthma” is classified in ICD-10-CM by severity and pattern before anything else — intermittent, mild persistent, moderate persistent or severe persistent — and each of those then separates an uncomplicated encounter from one with an acute exacerbation or with status asthmaticus.

5 coding concepts · 20 codes

The ICD-10-CM count is capped at 39: the search stops counting there, so the registry may hold more.

  • Understood as a diagnosis or condition search, so ICD-10-CM is ranked first.

Search results are not a code assignment. Review the documentation, official coding instructions, and applicable rules before selecting a code.

Coding pathways
